How many blood groups... Which ones are rare?
Normally human blood is of groups A, B, AB, O. These groups are determined based on the antigens present in the red blood cells. Group A if A-antigen, Group B if B-antigen, Group AB if both, O if none Otherwise considered as O group. Also RH factor on red blood cells is considered positive. If not negative. This means that if there is an RH factor along with the antigen on the red blood cells it is positive, Otherwise, it is called negative.
According to the World Population Review website, A-positive blood is 21.8%, A-negative blood is 1.36%, B-positive blood is 32.1%, B-negative blood is 2%, AB-positive blood is 7.7%, And AB-negative blood is 0.48%. O positive 32.53%, O negative blood 2%.
Looking at these statistics. It is very easy to understand which of these are the rare blood groups. Nationwide, AB-negative blood is available in only 0.48% of the population, while O-negative and B-negative blood are present in very few people.
In addition to the AB positive, AB negative, and O negative blood groups, there are two other extremely rare groups. One of them is the Bombay Blood Group and the other is the Golden Blood Group.
What is Bombay Blood Group?
All blood groups have names like English alphabets A, B, O. But this blood type has a city name. There is a reason behind this. It was first discovered in 1952 in Bombay, the capital of Maharashtra, India.
Finally those who have that group blood tend to think of their ‘O’ group blood. But when the 'O' group transports the blood to them after the blood donation does not match them, only through special tests can their blood group be determined.
It avai1 only about one in every 10,000 people
People with Bombay blood type do not have A, B, H antigen. Therefore, A, B, AB blood group is not included in the test. That is why many people are under the illusion that theirs is an 'O' blood type.But an 'O' cell test must also be done to test it in detail. If the blood belongs to the 'O' blood group, there will be no reaction on that test. But the presence of antibodies in the 'Bombay' blood group also causes a reaction with the 'O' cell. With that it seems to be the ‘Bombay’ group.
People with this group of blood are mostly found in Mumbai. This is because it is hereditary. This blood is coming from one generation to another. However, with some moving to other areas, those who currently have the 'Bombay' blood group are There are now a small number across the country, including the telugu states
What is the Golden Blood Group?
This Golden Blood Group is more rare than the Bombay Blood Group. In fact the name itself makes sense given how unique it is. Those who have this blood can donate blood to others But the saddest thing is that they can't find donors when they need blood.
In fact, the original name of this golden blood group was Rh null. Red blood cells in this group do not have the Rh antigen. This is why it is called Rh null.
This blood type was first identified in 1961 in an Australian woman, according to Mosaic, a website that provides details of medical research. Since then it has been revealed that only 43 people in the world have this blood
This blood is the most precious in the world, as well as the risk. Because, it is extremely difficult to find donors when those who have this blood need blood.It is difficult to trace the whereabouts of people with this blood in any country. They may not come forward to donate their rare blood if a donor is found.
On the other hand, those who have this blood are also called cosmologists. Because, they can donate blood to anyone. Moreover, Rh null works much better in saving lives compared to the blood of other groups.
It is unknown at this time what he will do after leaving the post. Some researchers are desperately looking for donors for samples to conduct research on this extremely rare blood. However, many were disappointed
Everyone should donate blood exactly once every six months. Because blood cannot be made
